A Russian dwarf hamster has probably been the best partner for H, a boy with autism. She has brought out the best in him and helped him in terms of emotional and social development than what any other person had already tried to do but with little success.
The hamster had also persuaded the boy to join his PE lessons. For H, a star chart for his hamster is just appropriate. The connection between effort and reward has suddenly “clicked” his mind and pursued him to do things in which he could gain rewards.
